Building the security layer for agentic software — before attackers do.
I lead AI Security Posture Management at Microsoft Defender, helping enterprises discover their AI agent footprint, detect misconfigurations, and assess and reduce risk efficiently, everywhere the agent runs. I write about what breaks as software becomes agentic in Context Window.

01About
Seven years in IDF Cyber Defense. Two companies founded — one acquired (NASDAQ: MGIC), one grew to 50+ people and became Microsoft’s #1 Azure partner in Israel. 8+ years at Microsoft building Defender. Two patents. Promoted to Principal PM to lead AI Security Posture Management in Microsoft Defender.
Now I build AI Security Posture Management from the ground up — agent discovery, risk scoring, attack path analysis, compliance mapping to EU AI Act and NIST AI RMF. I write Context Window and speak at global security conferences.
Posture used to be a photograph — a point-in-time scan that tells you how things stood. But agent risk is created at runtime. The question is no longer “is this configured correctly?” — it’s “given who’s asking, and with what authority, should this happen right now?”
